Yes, tungsten needles can be used for laser drilling and cutting of materials. Tungsten has a high melting point and is a good thermal conductor, making it suitable for use in laser cutting and drilling applications. Tungsten needles can be used as electrodes for electrical discharge machining (EDM) or as nozzles for laser drilling. They are also used as an electrode material for welding, especially for joining dissimilar metals. In general, the high thermal stability and excellent thermal conductivity of tungsten make it a popular material for laser processing applications.
